Networking Technology Overview
VDSL. VDSL (very high bit-rate DSL) operates over the copper wires in a phone line in a manner similar to
ADSL, but at much faster speeds. VDSL can achieve speeds as high as 52 Mbps downstream and 16 Mbps
upstream, as opposed to ADSL (up to 8 Mbps downstream and 800 Kbps upstream).
